BARBER S CHAIR.

Specification of Letters Patent.

Patented Dec. 24, 1918.

Application filed August 13, 1918. Serial No. 249,635.

To all whom it may concern:

Be it known that I, CHARLES PFANSCHMIDT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Barbers Chairs, of which the following is a specification, reference being h'adv to the accompanymg drawings.

In barber's chairs of the well-known hydraulic type wherein the chair seat is raised and lowered through the reciprocation of a plunger secured centrally to the under portion of the seat more or less of the surface of such plunger is exposed to view when the seat is in an elevated position, and as suchsurface is always covered with oil it presents an objectionable appearance and is very apt to become covered to quite an extent with particles of dust and lint. The greatest objection, however, to such exposure of its oily surface lies in the fact that small children will frequently place their hands on it and thus smear their hands as well as their clothing with oil. Furthermore, it has been known to happen that the barbers strop, hanging from the side of the chair, would so swing that its handle end would be swung into contact with such surface and so daub the handle with oil, thus causing the barber to waste time in cleaning the oil from such strop. The object of my invention is to provide a construction that will at all times so cover the plunger as to prevent such plunger from being brought into View when the chair seat is raised; that will make it impossible for any oil upon the surface of the plunger to be transferred to any person or article,

and that will present a neat and attractive appearance. Such object I attain by the means illustrated in the drawing and hereinafter particularly described. That which I believe to be new will be set forth in the claims.

In the drawings Figure 1 is a View partly in side elevation and partly in central vertical section of a barbers-chair of the hydraulic type in which is embodied my improvements;

Fig. 2 is a perspective view of the plunger; and

Fig. 3 is a perspective view of the upper and lower end portionsthe latter being in section-of the cylinder in which the casing moves.

Referring to the figures of the drawinga indicates a base from which rises centrally a hollow cylindrical casingv I) having an open upper end. 0 indicates a cylinder arranged centrally of the casing b and secured at its lower end in any suitable manner to the base a. This cylinder is closed at its lower end to adapt it to contain the oil by the pressure of which the plunger that is located in said cylinder is moved. As shown, a-flange d of the cylinder is bolted to thebase a and serves to retain such cylinder in place. 6 indicates the plunger referred to. It is made in the form of a hollow cylinder to adapt it to receive the usual pumping means that act to force the oil therefrom through a suitable valved passage to the lower part of the cylinder 0 whereby by its pressure against the lower end of the plunger such plunger and the chair-seat carried thereby are moved upward. The seat frame is indicated by A and the back hinged thereto by B. The actuating mechanism may be of any well-known form of construction and as it in and by itself forms no part of my present invention I do not here illustrate it in detail other than to show a reciprocating pump-rod which is indicated by f, which extends down into the hollow plunger, and the upper end of which will be connected to a crank on a rock-shaft that will be rocked by means of a handle g.

As generally constructed heretofore the cylindrical plunger 6 has had made integral with it an enlarged hollow head portion in which was journaled the rock-shaft before mentioned, and upon which plunger is secured the chair-seat frame A. I retain such head memberherein indicated by hbut form it separate from the hollow plunger and bolt such two parts together, so making suchhead member in order that there may be formed with it the protecting device that I employ to surround the piston. With such protecting member added to the head as an integral part thereof-and it is important for the sake of the appearance of the device to make it-integralit is necessary that the plunger be made as a separate part in order that the machining of its surface be properly performed to insure it having the required sliding fit in the cylinder 0. As shown, the lower marginal portion of the head is turned inward to form an annular flange i which rests upon an outturned annular flange j formed near the top of the plunger e,retaining bolts 7c passing through the two flanges.

Z indicates a cylindrical apron or protector formed integral with the head it and of such a diameter as to enter and have a sliding fit in the casing Z). Such protecting member Z is to be made of a length that will cause it to be always projecting into the casing even when the plunger 6 has been forced upward to its highest seat-holding position, and thus such plungerwill at all times be efiectually guarded and contacwith its oily surface prevented. m indicates an angular finishing ring secured over the upper edge of the casin Inasmuch as the cylindrical protecting apron Z is arranged concentrically with respect to the plunger'e and is carried by the same head it it follows that such apron will have the same slnooth action that'the plunger is compelled to have; and as the apron is to be given the same coating of white enamel as is ordinarily applied to the exposed surfaces of the other metal parts it in no way mars or detracts from the appearance of the chair as a whole, but rather contributes to such appearance.

What I claim as my invention and desire to secure by Letters Patent. is

1. In a barbers chair, the combination of a hollow cylindrical casing open at its upper end, a cylinder supported centrally in said casing, a reciprocating plunger fitted in said copies of this patent may be obtained for cylinder, a hollow head for supporting the seat of the chair and having an inwardlydirected flange at its lower end, means for removably connecting the upper end of said plunger with said flange, and a depending cylindrical apron connected with said head and projecting into the space between said casing and cylinder.

2. In a barbers chair, the combination of a. hollow cylindrical casing open at its upper end, a cylinder supported centrally in said asing, a reciprocating plunger fitted in said cylinder, a hollow head for supporting the seat of the chair, means for removably connecting the upper marginal portion of the plunger withthe lower marginal portion of the hollow head, and a cylindrical apron depending from said head and projecting into the space between said casing and cylinder.

3. In a barbers chair, the combination of a hollow cylind *ical casing open at its upper end, a cylinder supported centrally in said casing, a reciprocating plunger fitted in said cylinder, a head on the upper end .of said plunger for supporting the seat of the chair,

said plunger and head having flanges at their upper and lower ends, respectively, securing bolts passing through such flanges, and a depending cylindrical apron integral with said head, said apron projecting into the space between said casing and cylinder.
